INTRODUCTION
Three generations of pride in quality manufacturing and design improvements are built
into all U-Line products.
We are proud and excited to announce the latest edition to the U-Line family of products,
the CLR60, a 60-pound clear ice maker. We have been developing this product for over
two years and are excited about the quality and features which are unmatched by any
other model in its class. In addition to producing more ice than all other models in its
class, the U-Line CLR60 offers new, patented technology. We have reduced water consumption by 50% per pound of ice compared to some other models on the market. The
CLR60 has the easiest self cleaning process of any model in its class. All clear ice makers require periodic cleaning due to minerals in the water. We have simplified this
process through our electronic control which means ease and convenience for our customers. This model also uses a commercial-grade water circulation pump which is permanently sealed and lubricated, this pump increases the life and performance of the ice
maker. This pump requires no maintenance.
Finally, we have developed an exclusive drain pump for those installations in which a floor
drain is not available. The U-Line P60 pump is a fully submersible, self lubricating pump
that requires no maintenance. It is sealed to prevent water overflow in the event of a
power failure or drain line restriction and is fully integrated into the automatic shut off
feature of the CLR60 with a “quick connect” plug right into the power cord. The P60
pump is available only through U-Line or our Distributors and Dealers.
This service manual contains specific instructions for servicing U-Line’s newest model the
CLR60 - Clear Ice Maker.

Service and Parts Manual
Warranty Statement
On 11-1-98, U-Line Corporation modified the warranty provided with our units. We have
significantly improved the coverage of the sealed system in years two through five of the
unit’s life. The new warranty covers parts and labor for one year from the date of purchase. In years two through five, from the date of purchase, the warranty covers parts
and labor for the entire sealed system. The sealed system consists of the compressor,
condenser, evaporator, heat exchanger, dryer, hot gas bypass-valve and all connecting
tubing.
This decision reflects our continuing commitment to strive to maintain the leadership
position within the under counter refrigeration and ice making industry whether that be
through design, product innovation, or enhanced consumer warranties. This decision
reinforces the confidence that U-Line has in the performance and reliability of our products.
Our previous warranty covered parts and labor for one year from the date of purchase
plus four additional years for the compressor, part only.
The new, modified warranty applies only to units shipped after 11-1-98. All units
shipped before 11-1-98 have the previous warranty.
PRODUCTS SHIPPED BEFORE 11-1-98 - Warranty covers parts and labor for one year
from the date of purchase, plus four additional years for the compressor (part only).
PRODUCTS SHIPPED AFTER 11-1-98 - Warranty covers parts and labor for one year
from the date of purchase and covers parts and labor for the entire sealed system for
five years.
DETERMINING SHIP DATES
In order to assure that U-Line is Y2K compliant, we have recently completed a major
computer system modification. The new computer system has lead to changes in the
way we operate in most areas of the company. You’ll soon notice that our packing lists
are different, our invoices are different, our checks are different, and more. The change
that will impact you the most is the change in serial numbers.
With the new computer system, our serial number format has changed. There are some
definite advantages that go with the new format, such as being able to tell the month
and year in which the unit was produced.
The new serial number format breaks the number down into four segments. A typical
serial number is 99 918-06-9351. The first segment -–99, represents the year that the
unit was made. The second segment – 918, represents the shop order number. This
can be a three or four digit number. Order number 918 is assigned for Model 29 Black
–00 units made in June. The third segment – 06 represents the month that the unit was
made. The forth segment – 9351 represents a sequence of numbers that is used internally at U-Line Corporation.

WARRANTY CLAIMS PROCEDURE
When submitting claims for warranty payment, please follow these guidelines.
You can use any form you would normally use to bill your customer (your own computer
generated form, Narda, USA, etc.).
The model and serial number MUST be on the claims. Claims will not be paid without a
model and serial number.
If you work on more than one unit per service call please submit a separate claim for
each unit.
We track all defects through warranty claims, so please be specific on what the repair
was. If it is a system leak, please specify where the leak was.
Please be sure the claim is legible. If the claim form cannot be read, it will be returned,
unpaid.
U-Line will not cover part or labor claims for the replacement of a complete ice maker
assembly. All ice maker parts are available as replacement parts and are stocked in our
inventory. Remember: we do not pay customer education calls. Door and water level
adjustments are 90 day warranties only.
If you are changing out a unit please supply the model and serial number of both units
(the unit being replaced and the new unit) and the R.A. number.
Occasionally the customer does not return their warranty cards. In this case we use the
date the unit was shipped to our distributor for a beginning warranty date. This may
cause the claim to be rejected for a proof of purchase. If you want to check on a purchase date, you may contact the U-Line Corp. Customer Assurance Department at
1-800-779-2547. This will allow you to get a proof of purchase, if needed, before you
submit the claim.
At U-Line, parts and labor claims are paid separately. Included in labor would be freon

Service and Parts Manual
LEVELING AND INSTALLATION REQUIREMENTS
The objective of this section is to assist the
service technician in diagnosing problems that
are related to installation and/or leveling.
It is extremely important that the unit is level.
If it is not level, the ice mold will not fill evenly.
This can cause a reduction in ice rate, uneven
sized cubes or water spilling into the storage
area which will cause the ice in the bin to melt
prematurely. See Figure A.
Remember that floors near drains have a tendency to slope towards the drain.
UL307
Figure A
Leveling the Unit
1. Use a level to check the levelness of the icemaker from
front to back and from side to side. See Figure B.
2. If the icemaker is not level, adjust the feet on the corners of the unit as necessary. See Figure C.
UL215
Figure B
3. Check the
levelness
after each
adjustment
and repeat
the previous steps
as necessary until
the unit is
level.

UL205
Figure C
Installation Requirements
• The unit may be built into a cabinet. There is no minimum clearance requirement for
the top, left or right sides of the unit.
• The location must allow enough clearance for water, drain, and electrical connections
in the rear of the unit.
• The location must not obstruct air flow to the front of the unit.
10
GRAVITY DRAIN INSTALLATION
!
Plumbing installation must observe all state and local codes.
These guidelines must be followed when installing drain lines to prevent water from flowing back into the ice maker storage bin and potentially flowing onto the floor causing
water damage:
• Drain lines and fittings must have a 5/8 inch inside diameter
• Drain lines must have a 1 inch drop per 48 inches of run (1/4 inch per foot) and
must not create traps
• The floor drain must be large enough to accommodate drainage from all drains
• Insulate the bin drain line to prevent condensation
If water is backing up into the storage bin, it will be the result of one of the above points
not being followed. Below are examples of gravity drain line installations for your review. If
there must be a trap in the drain line, it is critical that the drain line is vented to assure
proper draining. Without the vent, water will backup until enough pressure builds up to
force the water past the trap. The problem is that the water may backup into the ice bin
before the amount of pressure needed is achieved. Water in the storage bin will cause
the ice in the bin to melt prematurely.
The customer’s complaint will be slow ice production because the ice that has been
made is melting prematurely due to water backing up in the ice bin.

Service and Parts Manual
CONNECTING A DRAIN PUMP
!
Plumbing installation must observe all state and local codes. All water and
drain connections MUST BE made by a licensed/qualified plumbing contractor.
Failure to follow recommendations and instructions may result in damage
and/or harm.
If a gravity drain connection is not available, and you have not purchased the CLR60 with
factory installed pump, install the U-Line P60 drain pump in the rear compartment of the
ice maker. The U-Line P60 drain pump is available through your Dealer, or direct from
U-Line with complete installation instructions.
If a gravity drain connection is not available, and you have not purchased the CLR60 with
factory installed pump, U-Line strongly recommends the use of the U-Line P60 drain
pump. If a pump other than the U-Line P60 drain pump is to be used, it must meet the
following specifications:
•
•
•
•
It must be UL listed and have a UL listed, 120 VAC, 3-wire grounded power cord.
Overall maximum outside dimensions of 8-3/4" wide x 5-3/4" deep x 7-3/4" high.
Minimum flow rate of 15 gallons per hour at 10 feet of lift.
It must have a sealed sump which does not allow water leakage in the case of a power
outage, restricted drain or pump failure.
• It must have a check valve in the discharge line to prevent waste water return to the
pump.
• It must have an overflow protection control which will shut off power to the ice maker
in the event of a pump failure.
• Operating temperature range of 50°F to 110°F (10°C to 40°C).
In the event of a power outage, restricted drain or pump failure, the failure to use the
U-Line P60 drain pump or a pump with the above listed specifications, could result in
substantial water leakage and pooling with severe and costly water damage and related
consequential damages and harm.

AUTOMATIC CLEAN CYCLE INSTRUCTIONS
Automatic Clean Cycle
To maintain operational efficiency, clean unit every six months (depending on water conditions more or less frequent cleaning may be necessary). If the ice maker requires more
frequent cleaning, consult a qualified plumber to test the water quality and recommend
appropriate treatment. Use only U-Line Ice Machine Cleaner (part number 41978).
!
Use only U-Line Ice Machine Cleaner (part number 41978). It is a violation of
Federal law to use this solution in a manner inconsistent with its labeling. Use
of any other cleaner can ruin the finish of the evaporator and will void the warranty. Read and understand all labels printed on the package before use. Ice
machine cleaner is used to remove Lime scale and other mineral deposits.
Refer to the following steps for mineral deposit removal.
1. Set the cycle selector switch (located in the center of the
grille) to OFF and allow the ice to melt off of the evaporator.
2. Remove all ice from the storage bin.
3. Remove inside front cover by gently pulling away from sidewall. See Figure A.
4. Remove the overflow tube by lifting it up while using a slight
back and forth motion to loosen it from the drain hole. See
Figure B. The water in the reservoir will flow down the drain.
5. Replace the overflow tube after all the water has been
drained from the reservoir.
6. Move the cycle selector switch to the CLN position.
7. When water begins to flow over the evaporator, (approximately 3 minutes) add one packet of U-Line Ice Machine
Cleaner to the reservoir.
8. Reinstall inside front cover.
9. When the self cleaning process stops (approximately 45
minutes). At this time, it may be desirable to clean the
storage bin. (See INTERIOR STORAGE BIN CLEANING)
10.Move the cycle selector switch to the ICE position to
resume ice production.

Service and Parts Manual
U-LINE CLR60 SEQUENCE OF OPERATION
On initial start-up or restart (closing of bin thermostat), the toggle switch is in the ice
position:
1. The water solenoid valve and hot gas solenoid valve are opened (energized) for 180
seconds (3 minutes). This ensures that the icemaking cycle starts with fresh water,
and that the refrigerant pressures are equalized prior to compressor start-up.
2. The compressor starts 175 seconds after the hot gas solenoid valve and water solenoid valves are opened.
3. The water pump and condenser fan motor are energized, and the hot gas solenoid
valve and water solenoid valves are de-energized (closed) five seconds after the compressor starts. The unit is now in the freeze cycle.
4. As the water pump circulates the water, an even flow is directed across the evaporator and into each cube cell, where it freezes. As the water freezes, gravity causes
any sediment to drop into the water trough and not becoming imbedded in the ice.
This gives a clearer cube with low mineral content.
5. The control system automatically determines the length of the freeze cycle by monitoring the temperature of the refrigeration system “high side” using a thermistor.
6. One minute prior to finishing the determined freeze cycle, the control determines the
length of the harvest cycle by again monitoring the temperature at the thermistor.
7. When the freeze cycle is completed, the control de-energizes the water pump and
the condenser fan motor. The compressor remains running during the harvest cycle.
The control then energizes the hot gas solenoid valve and water solenoid valve for the
duration of the harvest cycle. The hot refrigerant gas warms the evaporator causing
the cubes to slide, as a sheet, off the evaporator and into the storage bin. At the
same time, the water trough is being purged with fresh water.
8. At the conclusion of the harvest cycle, the machine returns to a new freeze cycle. The
compressor continues to run. The water pump and condenser fan motor are energized.
The hot gas solenoid valve and water solenoid valves are de-energized (closed).
Automatic Shut-off
The ice machine shut-off is controlled by the level of ice in the ice storage bin. When the
bin is full, ice contacts the bin thermostat bulb holder, which senses the cool temperatures, then opens which stops the ice machine. The ice machine remains off until
enough ice has been removed from the bin or has melted that the ice cubes are
no longer in contact with the bin thermostat bulb holder. This causes the bin thermostat
to warm and close, restarting the ice machine. When the ice machine restarts, it
returns to the start-up sequence (steps 1, 2, and 3 above).

THERMISTOR
The thermistor senses the refrigeration system “High side” temperature. This is used in
conjunction with the control board to determine the length of the freeze and harvest
cycles.
Thermistors generally fail due to moisture or physical damage. U-Line “high side” thermistors are encased in a specially-designed, moisture-sealed aluminum block. The thermistor is also mounted to the “high side” or “dry” portion of the refrigeration system. This
eliminates physical damage and moisture concerns.
Check Procedure w/LED Light on Control Board
The LED light on the control board serves three functions.
1. Steady light 2. Slow flash -
3. Rapid flashing -
The control board has power to it. There are no sensing
problems and operation is normal.
The control board has detected a sensor problem. This will
happen if the thermistor’s plug is disconnected from the
control board. This will also happen if the thermistor fails
open.
This indicated that the control board is receiving a high heat
signal from the thermistor. This can be caused by a dirty
condenser, inadequate air flow (unit installed behind closed
doors), failed condenser fan motor, etc.
In both the slow flash and rapid flashing situations, the unit will stop operation.

Low Side Pressure Changes
The chart above shows the low side pressure changes through the cycles of a CLR60 unit.
It shows that during a harvest cycle, the low side pressures climb to nearly 60 psig. When
the freeze cycle starts, the pressure quickly drops to approx. 17 psig and throughout the
freeze cycle it continues to slowly drop to approx. 7 psig just before the harvest cycle.
This unit was operating in a 75° farenheit ambient temperature and the incoming
water temperature was 50° farenheit.
If a unit is operating in conditions other than these, the low side pressures will be different. A unit operating in a warmer ambient environment or using warmer water will
have higher pressure readings. A unit in a cooler ambient environment or using cooler water will have lower pressure readings.

ICE THICKNESS ADJUSTMENT
The ice thickness control is factory set to maintain
an ice bridge of 1/16" to 1/8". A dimple in each
cube is normal. This size cube will break apart from
the slab easily as it falls into the ice bin. A fuller
cube, with less of a dimple, can be achieved by
adjusting the cube size. This will result in a thicker
ice bridge. As the ice bridge becomes thicker, the
tendency for the cubes to stay together as a slab
increases.
ICE BRIDGE SHOULD BE
1/16 - 1/8 INCH THICK
A DIMPLE IN EACH
CUBE CELL IS NORMAL
UL250
If an adjustment is needed, perform the following steps:
!
!
Do not touch electrical wires. Disconnect power to the ice maker before
making any ice thickness adjustments.
1. Disconnect power from the unit.
2. Remove front access panel (2 screws).

Cause
■ No electrical power to the unit
■ Rocker switch set incorrectly
■ Drain tube is kinked or obstructed
■ Bad pump. Diagnose by bypassing
the pump. Pull both pink wires from
control board and jump the two
terminals together. If unit starts up,
then the pump is bad.
■
■
■
■
Remedy
Make sure unit is plugged in and outlet
has power
Check switch wiring. Set to “ICE”
Clear the tubinga
Change pumpb
a: If water cannot drain from pump, unit will shut down due to safety design of pump.
b: Jumping the two terminals on control board together with a jumper wire will eliminate
pump from the circuit.
2. Unit Does Not Operate (Without drain pump; light on control board is not illuminated)
Cause
■ No power to unit

■ Re-circulating pump is defective
■
22
Remedy
Check that water is connected and
turned on
Insert stand pipe securely into water
trough
Replace re-circulating pump
5. Low Ice Production
Cause
■ High ambient temperatures around unit ■
■ Deposit build-up on evaporator grid
■
■ Ice thickness dial set incorrectly
■ Dirty condenser coil
■
■
Remedy
Lower ice rate is normal with high
ambient temperatures
Run the unit through a clean cycle. Use
only U-Line Ice Machine Cleaner
Adjust ice thickness dial accordingly
Clean condenser coil
NOTE: Light on control board will indicate if condenser is too dirty. A rapid flash of light
indicates high heat conditions which could be caused by either an inadequate air flow or
a dirty condenser.
6. Will Not Eject Ice (Water Frozen)
■
■
■
■
Cause
Bin thermostat set incorrectly
Wiring plug off of bypass valve coil
Defective bypass valve
Deposit build-up on evaporator grid
■
■
■
■
Remedy
Set bin thermostat at 10:00 position
Re-install plug
Replace bypass valve
Run unit through the clean cycle. Use
only U-Line Ice Machine Cleanere
e: If scale or mineral deposits accumulate on grid, cubes will not fall freely.
7. Ice Is Slow To Release From Evaporator
Cause
■ Deposit build-up on evaporator grid
■
■ Unit not level
■
Remedy
Run unit through the clean cycle. Use
only U-Line Ice Machine Cleaner.
Level unit for even water flowf
f: Uneven water flow will reduce ice rate and cause water to spill in ice bin.
8. Will Not Fill With Water
Cause
■ No stand pipe in water trough
■ Water valve is defective
■ Water solenoid unplugged
or wire to solenoid has internal break
■
■
■
Remedy
Install stand pipe
Replace valve
Repair wiring defect
■
■
Remedy
Set bin thermostat to the 10:00 position
Insert bulb inside aluminum sensor tube
9. Continuous Ice Production
Cause
■ Bin thermostat set too cold
■ Bin thermostat sensing bulb out
of alignment
■ Bin thermostat stuck in closed position
■ Ice slab too thick
■
■
Replace bin thermostat
Set ice thickness adjustment dial to a
lower settingg
g: If cubes release from grid and are too thick, cubes might not make contact with
sensor tube (inside of bin) therefore bin thermostat would never be satisfied.
23
Service and Parts Manual
10. Low (or no) Ice Production
Cause
■ Dirty condensing coil (Control board
light shows rapid flash)
■ Stalled condenser fan blade (Control
board light shows a rapid flash)

■
■
Replace thermister
Replace control board
h: uneven water flow will reduce ice rate and cause incomplete cubes. See Leveling
Instructions in manual.
i: the unit will harvest ice according to temperatures of tubing at condensing coil.
Increased air flow will give the thermister false information. This info could cause the
ice to eject prematurely.
14. Not Freezing Compressor Not Running / Fan Operating
